This game is an update to the classic Mario Brothers arcade game which was also the Super Mario Brothers 3 mini-game. You hit the platform the enemy is on, then touch the enemy to kill it. This classic game has been updated to include 50 new levels, each with its own design (unlike the original). It also adds new enemies based on other Mario games. This version uses the full 128 pixel width of the TI-85, so you get a leg up on the TI-83 users. Check out this great update to a great classic game.
